| Abstract: | In this paper, a video compression algorithm based on the H. 263 standard is presented. For desk-top video conferencing over low bandwidth lines, to make an implementation of this standard applicable for real time purposes, the motion estimation, DCT, and quantization algorithm are the most important points, especially application of motion estimation algorithms must be done correctly to make them efficient with regard to compression ratio and computing speed. |
